.If Rolfe, 65, is deemed competent to stand trial in the death of his sister, Judith Rolfe, 66, attorney Timothy Landry said Monday that he will rely on an insanity defense.

Dr. Philip Kinsler, a clinical and forensic psychologist, performed the evaluation, according to Landry, who expects the results of that evaluation to be available within a few days..."There is an issue of competency," Landry told the court, requesting that a second evaluation be conducted closer to the date of the upcoming competency hearing, which has not yet been scheduled.

"I think I would be remiss to state one now," he told the court...Landry believes his client is currently incompetent to stand trial, but he said Rolfe is working with his legal counsel.

Under law, the defense has 30 days from the arraignment date to announce whether it intends to utilize an insanity defense, Agati said, explaining it is not uncommon for competency issues to be raised early in the legal process...Also on Monday, Rolfe's attorney asserted his client's right to a speedy trial, requesting that the case be tried within six to eight months. Agati said that "hard and fast" deadlines will have to be implemented to ensure a trial within that time frame...Judge Diane Nicolosi asked that the request for a competency hearing be placed in writing as soon as possible..."It has to be within 60 days," said Nicolosi.
